I will try. Sorry I'm new user. edit: According to your link , that guide about add WMC to windows 8.1. But after I added , my pc is not activated. Should I do? or How to remove WMC feature from windows 8.1.
Do not use Win 8 Pro WMC key here . Use the key given at top of Titos first link . Will work with added WMC, as tested.
I used my old windows 8 wmc key . I entered a key in the first post and it display in the picture below.
The key you show is the Win 8.1 Retail Key, and since you added WMC that KEY is no longer good, You have to enter the Win 8.1 WMC Key... if you want WMC.... if you do not want WMC then you have to 1. Restore back to before you added the WMC Key. 2. You can always Clean Install again 3. If you know the proper method to "UPgrade or Downgrade" you can also do that... 4. I have validated that works - a. went from Win 8.1Pro to Windows 8 Ent 5. I have validated that works - b. went from Win8.1ProWMC to Win 8.1 Pro YOU do need the proper DVD as will be requested. Im sure there are other methods to do this. I did the method as above.
